Julian Castro to deliver DNC keynote

7/31/12 7:21 AM EDT

Univision's Jordan Fabian reports on the keynote speaker at President Obama's nominating convention — an up-and-coming Latino mayor from Texas:

San Antonio Mayor Julián Castro will deliver the keynote address at the Democratic National Convention in September, becoming the first Latino ever to be chosen for the prestigious slot.

Castro, 37, will address the crowd on the opening night of the convention on Tuesday Sept. 4 in Charlotte, N.C., where Democrats will officially renominate President Obama for a second term. Castro’s prime speaking spot is sure to stoke speculation about his political future, since Obama’s keynote address in 2004 helped launch his national political career. As is tradition, also speaking that night will be the First Lady, Michelle Obama.

In a video announcement, Castro recalled being inspired by Obama’s speech four years ago, especially his “the promise of America where everyone has a decent shot at life.”

The DNC keynote, of course, is where Obama catapulted into the national spotlight with an uplifting speech at the 2004 Democratic convention in Boston.
